|
Altro: Control group
patients awaiting for evaluation to cardiac rehabilitation or transplantation
|
No intervention during the 8-weeks period of the study because of awaiting evaluation for cardiac rehabilitation or transplantation
|
|
Sperimentale: moderate-intensity group
Patients will be submitted to a 8-weeks training program, with inspiratory muscle trained at 30% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with upper and lower exercises (50% of the 1-maximum repetition test).

Patients will be submitted to a 8-weeks training program with inspiratory muscle trained at 30% of the maximal inspiratory pressure (30 minutes/session/7 days/week) + peripheral muscle trained with exercises of upper limbs and lower limbs (50% 1 RM, increased every 2-weeks).
|
|
Comparatore attivo: low-intensity group
Patients will be submited to a 8 weeks training program, with inspiratory muscle trained at 15% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with exercises of upper limbs and lower limbs (0,5 Kg each).

|
|
Change in heart rate variability (HRV)
Lasso di tempo: Before and after 8-weeks
|
HRV is obtained from the spectral analysis of R-R intervals obtained from a heart rate monitor (Polar, S810, Kempele, Finland)
|
Before and after 8-weeks
|
|
Prevalence of cardiac events and arrhythmia
Lasso di tempo: Before and after 8-weeks
|
by a 24-hours holter system for continuous recording of ambulatory electrocardiographic signs
|
Before and after 8-weeks
|
|
Change in international Physical Activity Questionnaire (IPAQ)
Lasso di tempo: Before and after 8-weeks
|
Patients will be classified as sedentary, irregularly active, active or verry active according to Matsudo's classification (2001).
|
Before and after 8-weeks
|
|
Change in quality of life using Minnesota Questionnaire
Lasso di tempo: Before and after 8-weeks
|
by Short Form-36 and by Minnesota Living with Heart Failure Questionnaire - Minnesota living with heart failure questionaire: contains 21 questions of physical, social, economic and emotional aspects. Each question ranges from zero to five points, with a total score of 105 points which is the maximum severity degree related to personal perception of quality of life. |
Before and after 8-weeks
